Abstract

A rotor for a reluctance motor includes a laminate stack having layers. Each layer has a plurality of flux-conducting sections formed in each case by a magnetically conductive rotor lamination and extending transversely to a corresponding q axis. The flux-conducting sections are separated from one another by nonmagnetic flux barrier regions. An electrically conductive and non-ferromagnetic filler material is arranged in a plurality or all of the flux barrier regions of the layers to electrically connect the flux barrier regions of adjacent layers to one another so that cage bars of a rotor cage of the rotor which extend axially parallel or skewed with respect to the axis of rotation are formed by the filler material in the flux barrier regions.
